This is how you delay a Serious Sam game: a silly little in-engine gag that someone threw together.
Forget everything you know about August – at least as it pertains to long-time-coming shooter sequels. Croteam delayed the Steam and Stadia release of Serious Sam 4until September 24, 2020. The circle-strafing, horde-slaying chaos will have to wait. Don't forget to tell your co-op buddies.
In case you missed it, the console versions aren't arriving until next year. Screw the skeletons.
